There were hundreds of watch makers / assemblers that used electric and electronic movements in the 1960s and 1970s. The list above only represents those makes where I own an example. If you have some other make that is not listed and you want some help, advice or just want to show me, please do get in touch using the email link on the home page...I'm always interested in seeing other makes of electric watches!

I know nothing about this maker, sorry, but it appears to be new-old-stock
and comes complete with its original rally strap.
Houses the fairly common ESA 9154, a Swissonic movement.
Look at that balance go!
